"It can be seen that mental health is based on a certain degree of tension, the tension between what one has already achieved and what one still ought to accomplish, or the gap between what one is and what one should become. Such a tension is inherent in the human being and therefore is indispensable to mental well-being. I consider it a dangerous misconception of mental hygiene to assume that what man needs in the first place is equilibrium. What man actually needs is not a tensionless state but rather the striving and struggling for a worthwhile goal. What he needs is not the discharge of tension at any cost but the call of a potential meaning waiting to be fulfilled by him."
